He wiped down the shotgun wearing gloves so that there would be no fingertips and shaved his face and head so that he wouldn't leave behind any forensic evidence, the complaint says.

He had already driven to Jayme's home twice before. The first time he was scared off by cars in the driveway. The next time, he left after spotting lights and people in the house, Patterson told investigators, according to the complaint.

On his third attempt, Patterson did not back down.

Jayme told investigators she woke up to her dog's barks and saw a vehicle in the driveway.

A chilling tale of murder, kidnapping and escape in rural America

As the young girl hid in the bathroom with her mother, Denise, James Closs went to the front door, where he was shot and killed. Patterson shot Jayme's mother minutes later, the complaint says.

He pleaded guilty to killing the Closses and kidnapping Jayme and was sentenced in May to life in prison without parole.

He received one life sentence for each of the murders of James and Denise Closs and was given a 40-year sentence for the kidnapping, including 25 years in prison and 15 years on parole.

"Jake Patterson took a lot of things that I love away from me," Jayme said shortly before the court's decision in a statement read by her attorney.

"It makes me the most sad that he took away my mum and my dad," she said.

"I used to love to go out with my friends. I love to go to school. I love to dance. He took all of those things away from me, too. It's too hard for me to go out in public. (Patterson) should stay locked up forever."

Patterson said he would do "like, absolutely anything" to take back what he did and would "do absolutely anything to bring them back."
